' Specification of Letters Patent.

Application filed January a, 1916. Serial No. 73,421

Toall whom it may concern a i lie it known that 1, RALPH J. QUELLE, a citizen of the llnited States of America, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain' new and useful Improvements in Valve Systems, of which the following is a SIiQUlfiCzllllUll, reference being had therein to the aecon'ipanying drawing.

This invention relates to engines and has special reference to a cylinder valve system which may be employed upon explosive engines'of any type, air or gas engines, and in fact any other suitable or desired motor 5 wherein the same mechanical construction or system may be adopted.

Another object vof this invention is theproduction of a simple and efiicient valve system for a four-cycle engine or motor, and

has [for its object the production of a simple and efficient means for feeding the gases to the explosive cylinders and conveying the exhaust gases therefrom at redetermined times through the medium 0 therotating valve.

i A. still further object of this invention is theproduction of a simple and eiiicient means for lubricating the rotating valve so as to cause the valve to operate'with the least amount of friction.

With these and other objects in view this invention consists of certain novel combi-' nations, constructions, and arrangements of parts as .will be hereinafter fullydescribed In the accompanying drawings :-Figure '1 is a' central longitudinal section through themotor showing the rotary valve in side elevation. Fig. 2 is a top plan view of themotor showing the manifold removed. Fig.

. 3 is abottom plan view of the upper section of the valve casing showing the rotary valve positioned therein. Fig. 4 is a top.

I plan view of the lower section of the valve casing, the rotary valve being removed therefrom. Fig. 5 is a top plan view of the explosive cylinders-with the upper valve casing removed or in other words a section taken on lihe'55, of Fig. 1,'lo0king in the Eli-direction of the arrow. Fig. (3 is a section taken on. line (i(3, of Fig. 1. Fig. 7is a' section taken on line-77, of Fig. 1. Fig. 8 a section taken on line S -8, of Fig. 1; Fig. 9 a section taken on line 1 4), of.

Fig. 1. Fig. 10 is a plan view slmwing the arrangement of the ports in the rotary valve, the valve being shown in diagram to more clearly illustrate the different arrangements of the ports. Fig. 1.1 is an embodiment of the invention wherein the valve casing is positioned to one side. of the explosive cylinder, thereby producing what is known as the L-head type. Fig. 12 is a vertical section through an embodiment of the in vention wherein two valves are employed, one above the explosive cylinder and one to the side thereof known the overhead and L-h'ead type. It, of course, should be on delstood that the valve may be so placed as to produce what is known as a. T-head type without departing from the spirit of the in vention by having two valve casings, one casing being positioned upon each side of the explosive cylinder. Fig. 13 is a trans-' verse sectional view through the upper section of the valve casing. Fig. 14 is a transverse sectional view-through the lowersection of the valve casing.

By referring to the drawings it will be seen that 1 designates the crank casing which is formed of aplur'ality of sections to facilitate the disassembling of the casing when so desired as is usual with such engines. crank shaft 2 is placed within the crank casing 1 and is journaled upon the standards 3 as illustrated in. Fig. 1 of the drawings. A fly wheel 1 of suitable construction is (Karried by the crank shaft 2, and the crank shaft 2 may be connected to any suitable mechanism which it is desired to drive by means of a connecting shaft illustrated in Fig. 1 of the drawings.

Acylinder supporting housing (3 comprising the upper half or section of. the crank casing is, supported upon the lower half of the crank-casing '1 as illustrated in Fig. 1, and is'provided with'a plurality of ports7 in the top thereof which communicate with the respective explosive cylinders hereinafter more fully described. The crank shaft 2 is provided with a gear 8 which meshes with a gear 9 carried by a stub shaft 10, and this shaft 10 carries a sprocket wheel 11 over which sprocket wheel 11 passes a sprocket chain 12, the chain 12 in turn passing over a sprocket wheel 13 carried by. the shaft 14 which supportstherotary valve 15. A sprocket wheel 16 is also. supported upon thccrank shaft 2, around which a sprocket chain may be passed it so desired for drivnalcd upon the explosive cy ing the valve 15direct from the shaft 2 ac-' cording to the direction of travel in which the valve 15 is desired to operate. A generator, magneto or water pump may be driven by means of a chain frointhis s rocket wheel 16. Apulley 17 is keyed to tie. shaft 5, and a fan supportingshaft 18 is supported upon the frame 10' as illustrated in Fig.- l and has its inner end jourlinder housing 20 as illustrated. in Fig. 1 of the drawings. A pulleyill is carried by the shaft 18, and a belt of suitable construction may pass over vthe pulleys 17 and 21 for the purpose of driving the fan 2'2 carried by the shaft 18 for the purpose of cooling the engine when so desired;

A plurality of explosive cylinders 20 are arranged upon the housing 6, and the explosive chamber 23 of these cylinders 20 communicates ,with the apertures 7 formed in, the housing (3. Although four cylinders 20 are preferablyused, it should be understood vthat an y number oftcylindersumay be used without departing from the spirit of the invention. Piston heads 24 are. mounted within the cylinders 23 and are-connected by means of piston rods 25 to the respective crank portions of the crank shaft 2. ,A suitable ;1vater jacket 26 may be employed around the explosive cylinder 20 as illustrated clearly in Fig. 1 of the drawings for the purpose of efliciently cooling the explo-w sive cylinder as is usual with such water Jackets.

A valve supporting casing is mounted upon the top of the explosive cylinders as avill be s' cen by carefully considering the drawings, and this valve casing comprises a lower section 27 and an upper section 28, which sections are adapted to efficiently register and-are provided with alongitudinally extending pocket for: fitting snugly around the rotating valve A hearing housing 29, is mounted ineach. endofiwthe valve supporting casingand supportsthe hearings f3(),'"\vhich bearings-fit snugly around the shaft portion 14 ofthe rotary.

valve 15. flhe several: sections comp-rising theuppcr and .lower sections of the valve casing maybe joined or, connected together i.n"any suitable or convenientmanner-d0! (,I.l using the sections to fit snugly around the valve, and by having. the sections formed so as to be readily separated, it will be seen' that the valve may be readily repaired or olcancd when so desired for the purpose of rt-moving carbon" therefrom, and, further that bymoving the entire v,alve"casing, access may be had directly to they top of the piston heads so as to permit the carbon to be rcadilyand con'veniently scrapeddlom the upper end of the piston heads. This: is a very important and. essential featurecjn connection with explosive engines, for by experience it has been found difficult to re- .move the carbon which accumulates upon the piston-heads and the upper end of the cylinder, ispvt'ially in view of the fact that it has been found practically impossible to obtaiii free access .to these portions of the engine in order that the carbon deposited thereon maybe readily removed. I It should be understood that as illustrated clearly in Fig. 6, a water jacket 31 is arranged around the rotary valve 15 and thereby keeps the ,same cool, the water of course, being supplied to, the, water jacket 31 in any suitable or convenient manner. An oil lubricating reservoir 32 is placed. around the outer portion ofthe water jacket, and the casings of the valve are provided with a pluralityof lubricating supply ports i3 for conveying the lubricant at all times to" the rotary valve 15.1 It should be under stood that-thei oil by being confined in" the compartment 32 will be kept quite 0001 due to the fact that the-water jacket is inter- "posed -betw een the rotary valve and the oil compartment, thereby allowing the lubri-- cant to perform its function in the most efficient-manner. The lower section 27 of the valve casing is provided Witha plurality of zigzag grooves 34' formed upon the com; cave face thereof, which grooves will cause the lubricant to travel over the entire inner faee oflthe valve housing, thereby producing an'eflie'ient means for thoroughly lubricating the entire face of the rotary valve 15. These grooves 34 communicate Wit the ports 33 thereby permitting a constan supply-of l'ubricant to" pass to the grooves34. Attention is now called to the fact that each explosive cylinder 20 is provided with a spark plug receiving pocket 35 within which is mounted a spark plug 36, the spark plug beingfconneete'd inthe usual manner with atimerand means fon. supplying current thereto, which construction is tl ought unnecessary tov illustrate and describe in- .de- 119 -tail.. The "spark plugs. by being: placed. in

the pocket 35, willbe protected from injury i and will not be'likelyto become loose owing to the fact that the securing nut 37' carried 'therebvis-mounted clearly ithin the pocket 1 5.

35 which.supportsth-e spark plug 36. It should l)&- 1 ll1(leI'St00(l that the inlet aperturesBS and exhaust apertures or ports 39 are arranged in pairs as illustrated in Fig. 4 in alinement with each other and 15:0- communicate with the explosiy e vchambers 23 so as to permit the exhaust gases to be .dischargedtherefrom and the 1mm gases to adin itt'ed thereto when the proper apertures formed in therotary valve4 l5 12B ,register with the respect-imports 38 and 39. By ca refully.considering Fig. ii'and also the diagram view in Fig. 10 it will. be seen that the inlet ports 40 and i1 adaptedt'o co operate, with each explosive cylinder are v a rotary valve positioned within said detachable valve casing, said valve provided with a plurality of ports formed therein, said valve casing provided with' a plurality of ports c-onnnunicating with said ports in said valve and also communicating'with said explosive cylinders for controlling the passage'of gases to and from said cylinder through said valve, said rotary valve provided with a projecting end shaft. bearings snpportin said end shaft, means for supplying luliricant to the periphery of said rotary valve, a water jacket formed around said rotary valve within said valve casing, and an oil reservoir formed within said waive casing and positioned upon the outside of said Water Jacket for facilitating the cooling of the lubricant before being admitted to said rotary valve:

2. An engine of the class described coinprising an explosive cylinder, a valve casmg supported thereby, a rotary valve positioned within said valve casing, means for supplying lubricant to the periphery of said rotary valve, a water acket formed around said rotary valve within said valve casing, an

oil reservoir formed within said valve casing and positioned upon the outside of said water jacket for facilitating the cooling of the lubricant before being admitted to said rotary valve.

In testimony whereof I hereunto affix my signature.
